I have ~3000 miles on my Oct build e90 (330i S/P), and have noticed that the left exhaust emits considerably more black gook than the right.

Is there a specific reason for this? Is this something that I should be concerned with?

The right exhaust has a flap that opens only at higher load / revs. So when your on partial throttle (most of the time), you´re only using the left exhaust. Also there´s way moore soot buildup on partial throttle because the exhaust gases are flowing slower and there´s a less complete burning taking place in the engine.

should i be worried that this kid at school shoved alot little pebbles in my exaust? i was ready to kill him when he told me he did this. It happened over a week ago and i havent noticed any problems yet but i was just wondering?

No, nothing to worry. They´ll have been blown out. And please don´t kill the kid :

o i wasnt literally but if he continues to do more crap to my car ill consider it, like that same day i found a rock on my windshield, and then 2 days later (friday) when i was waiting to get out of school (there a line to leave) he stands in front of my car drops his shorts and wipes his ass on my car, i honestly felt like running him over! but thankfully i didnt, i mean i hear blood stains and i have a white car so it would be pretty messy lol

I dont know i think hes jelous, but he "claims" he has an escalade that is his but his dad is driving till he gets his license, hes 16 but waited a while to get his license. i dont know but if he does any more shit to my car, the gates of hell are going to open lol

Well if you arent able to do anything to him physically then just be sure to catch him doing shit to your car. If things get severe enough, just get a police report and take it to small claims court. On the side note though, he seems like he really hates you? Why are you letting him push you around like that? I go to high school as well and if i saw a dumb kid trying to do anything to my car i'd either pound his ass or call the cops to file a report then start pounding his ass. Either way, bloodshed would be neccessary for revenge.

I go to private school and i already threatened him by saying if he touches my car again (after he did the ass thing) i would tell the dean about everything you did, (my school has like a "zero tolerance" policy supposingly about messing with other peoples cars) and get you expelled, so far he hasnt done anything that i know of, knock on wood.

but ive had thoughts of just punching the kid in the face a couple times, he really gets annoying hes like im sorry that my daddy diddnt buy me a brand new BMW, ahh people can be soo frustrating when they act like idiots!

Hey im high school too. But there is one problem i have with the kids in my school. this one annoying girl saw my car and was like "O is that a 5 series?" i laughed and replied "No its the new 3" she said WOW i think i want to get that car. Then a month comes around and i see a 325i in jet black with SP, IDENTICAL TO MINE!. I approached her and was like hey whats the deal? she simply said "yea i wanted to get a nice car it was between this and the g35, but i like the bmw, well, because its a BMW!" I then paused and really wanted to maybe talk to this girl for hours, she has no idea what people buy bmw's for, At least what they are built for. ANYWAYS..... a week passes by and i see her pull up in a rental chevy cavelier. I told her is her car in service. She basically told me that she wasnt paying attention while driving and rear-ended someone at around 20-25MPH!!! This almost made me burst into tears.
I realize I am only a naive little kid in highschool(not 18 yet), But comeone there is no reason people should be so dumb. Even worse is that parents will give their child a car knowing that he/she probably will crash because he/she is not the most alert person in world(ADD/Immaturity). Wait sorry for stealing the thread. But 325baller, i feel you on some of those kids, but like in my school kids know that my car= my life. And i have given fair warning to anyone who tries any "funny-stuff" near my car. I actually saw one kid in the act of keying my car.... I then immediatly poped my trunk and chased the fucker with a lacrosse stick, I then had the kid on the curb of the street and began hitting him. memory is fuzzy because i was so angry i went into one of those rages. But i hit him once in the head then MANY times in the stomach and chest. Lets say he will have a bruise or two in the mourning. Weird part was, i hardly knew the kid who did it, ive seen him in school though, was one of those rebel kids. Good part of the story is that he only keyed about an inch before i had him running. SORRY AGAIN FOR GOING KIND OF OFF TOPIC!

what the hell kind of high school do you people go to? I had a 7 year old Honda Accord for my first car. Loved it. Personality. The gear shift wouldn't stay in drive... sometimes it would fall into neutral. I bumper stickered the thing from top to bottom, front to back. The back left speaker blew the third day it was mine.... andI never fixed it. The driver side door speaker would only work if you thumped the dashboard just above the radio.
I loved that car..... I hope you guys appreciate what your parents are doing for you. I know this sounds old and fogey... but read my signature.....
